Saying Hello & Asking Shock Questions

Hi,
Bit of a newbee here. (UK based)
Test rode a Husky 400 WR way back when. Wasn't the bike for me at the time. But its always lurked in the back of my head.
Long story short I tracked down a 1986 400 enduro in fair to good condition (American import). Just going through it and tiding it up with the intention of road registered for a bit of greenlane and general hooliganism.
Have the parts manual, workshop engine manual. But the one thing I'm struggling with is finding a manual / parts list for the Ohlins rear shock.

Any pointers would be most appreciated.

Cheers.
